Car runs rough and will die if not giving it gas, but runs fine when you go fast enough. When you unplug the MAF sensor, it will run fine, but it shifts gears really rough. Replaced the MAF and it still runs the same. Tried resetting the ECU, but can't find the right method, or it's not doing anything. Any advice

Classic accordion hose issue, check the hose behind the MAF. I had to duct tape mine for a while.

I had this issue and replaced the gaskets 6 months later I took the intake manifold off to clean it and when I put it back on now I’m having the same issue it won’t even idle it just starts and immediately stalls just like before. I am going to say it’s the gaskets again but if I take this thing off and have to replace the rubber gaskets every time that’s kinda defeats the purpose of maintaining the car.
